SPECIFICATION forming part of Letters Patent N 0. 380,156, dated March 27, 1888. Application filed December 7,1887. Serial No. 257,211. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES W. ZIEGLER, of Scranton, in the county of Lackawanna and State of Pennsylvania, haveinvented certain new and useful Improvements in Coal-Separaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same.

My invention relates to an improvement to the inventions described in patents numbered 277,530 and 29l,123,. granted to me May 15, 1883, and January 1, 1884, respectively, for improvements in machines for separating slate and other like impurities from broken coal; and it consists in the construction of theparts, their relation, arrangement, and combination with each other in completed machines, as will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 represents aside elevation view. Fig. 2 represents a top or plan view. Fig. 3 represents a longitudinal sectional view on lines a: w of Fig. 2, and Fig. 4. represents a horizontal sectional view on lines y y of Fig. 3.

A represents the supporting-frame of the actuating parts of the machine, and B the standard-supports thereof.

0 and O are cylinders rigidly secured to shafts D and D, which are mounted in suitable bearings in frame A. The cylinders may be rigidly mounted in said bearings against revolution, or may be loosely mounted therein, as preferred, and in the latter instance revolution can be communicated thereto by means of the pulleys E on said shafts D D. The cylinder 0 is on a lower plane than cylinder 0, as shown in Fig. 3. t I

F is an inclined chute, provided with perforations G andhinged to the'brace H. The object of perforating the chute is to enable the fine dust which escapes the screen to pass away from the coal when the same is dumped upon. the chute. The chute is located directly under the delivery-point from the screen, so as to receive the coal upon its inclined surface, the pitch of which is regulated as may be required to give the proper momentum to the coal as the cylinders C and O.

the diflerent grades of hardness and other conditions may require. The chute'is elevated and lowered by means of the lever I, secured to shaft K, which latter is mountedinthe braces L. To the shaft K-is secured the. depending arm M, the same'being connectedto a similar arm, N, on shaft 0 by means of therod P. The shaft 0 is mounted in bearingsP and has secured thereto the arms Q, to the ends of which are pivoted the levers R,'the opposite ends of said levers being pivoted to the chute F by means of the lugs S. The chute is elevated and lowered by oscillating the lever I, as shown in Fig. 3. 1 r

T is an incline having the curved upper end, U, with whichcurved portion the lower edge of the chute F is in constant contact- The incline T rests upon the platform W, which is, situated'on a level with the top of the cylin: der 0.

a a represent a series of inclines which are situated below the cylinders G and O. The upper ends of the said inclines are curved, as

' shown at a, and are overlapped at such curved portion by the oscillating curved gage-plates b, which plates constantly register with said curved portions a. The lower ends of the inclines a a rest upon the platforms d d. The

saidplatforms areon a plane with the tops '0 The inclines a a. are located a su-flicient distance from the cylinders to form openings cc between them of such size as to permit of the passage of the slate found in the largest-sized coal, the said openings being adjusted in size 8 5 by means of the gage-plates b, which are journaled in suitable hearings in the sliding bars '6. The journal ends of said plates work in the slots f,,formed in the frame A. The ends of the bars 6 stick in the guides h, located on the frame. p

The gage-plates b are adapted 'to be moved toward and away from the cylinders, thereby enlarging or closing the opening 0, according to the size of the slate running with the coal undergoing separation. This is accomplished by oscillating the levert, pivotally connected and other matter, having the propermomen-.

tum,will run down the inclines and thence onto the platforms. The coal, owing to its shape, will naturally run faster and with a greater impetus than the slate, which is usually flat,

and consequently slow in motion, and hence when the platform is reached the coal will retain its speed, striking and jumping over the cylinders and openings onto the plates 2) and the curved portions (1*, where it receives a new impetus from contact therewith. On the other hand, the slate, being flat, loses motion constantly, and when it strikes the platform it possesses only sufficient motion to enable it to strike the cylinder or curve and slide over the same into the openings 0 and thence into the troughs.

The cylinders and inclines may be of any desired number, although the two shown are sufficient for the purpose of illustration. The object of having more than one incline and cylinder is to insure a more perfect separation of the slate from the coal, for if the slate escapes one opening it is barely possible that it should pass two or more.

Having'fully described my inventiomwhat I claim as new, and desire to secure by Letters Patent, is

1. In a separator, the combination, with an adjustable chute, of inclines having curved upper ends, gage-plates registering withthe said inclines, and means for adjusting the said plates, substantially as shown and described.

2; In a separator, the combination, with an adjustable perforated chute, of inclines having curved upper ends, gage-plates adapted to engage the curved upper ends of the inclines, and a lever connected with the gage-plates for oscillating the same, substantially as shown and described.

3. In a separator, the combination, with an adjustable chute, of inclines having curved upper ends, cylinders above said inclines, and curved gage-plates adapted to engage the upper ends of theinclines, and a lever connected with said plates for oscillating them and regulating the size of openings, substantially as shown and described.

4. The combination, with the curved gageplates and theisliding bars 6, pivotally secured thereto, of the rod k and the arms j,secured to said rod, and thelever i,for actuating the same, substantially as shown and described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
